Burst and Leak Safety: Our hot water bottle is made with an innovative, age-resistant rubber that offers greater heat retention and longer life than traditional rubber. It also survived a crash test with a large truck without damage and can support up to 500 kg. Thanks to the thick screw valve on the opening of the bottle it is 100% leak-proof. Double Opening Design: This hot water bottle with lid has two openings where you can insert both hands to warm up comfortably. Premium Plush, Soft and Skin-Friendly: The hot water bottle cover is made of high-quality premium plush and has long-lasting heat retention. Machine washable. Safe and Convenient: The surface of the hot bag is specially designed with a textured structure that ensures even heat distribution and minimizes the risk of burns. For safety reasons the water temperature must not exceed 80 degrees Celsius and it is recommended to fill the bottle up to two thirds.
